Tony is building a new silo to store corn as animal feed. It will be a cylinder topped with a half-sphere, and must store 21 000

t of corn. The entire silo can be filled with corn. Tony wants to minimize the surface area of the silo to reduce materials and paint costs. He has the following information:
• 1 cubic m of corn has a mass of 700 kg.
• Building costs are $8/m2, taxes included.
• Paint comes in 3.8 L cans.
Each can covers 40 sq m and costs $35,
taxes included.
• Corn costs $140 per tonne ($140/t), taxes
included.
What is the total cost to build, paint, and fill a silo with the least surface area?

What Are the values of x and y?
dem82 [27]

Answer:

y = 72.5

x = 35.

Step-by-step explanation:

First Off, Let's Divide the question.

<em><u>Let's Find the variable y : </u></em>

<em><u /></em>

there are 2 y(s), so it is 2y.

equation:   2y +35   =180.

I put 180 because A straight Line is always 180.

2y+35=180

<u><em>1. Subtract both sides. </em></u>

2y =  145

y = 72.5

<u><em>Next,Find x </em></u>

So y + y + x = 180.

We already know y, which is<u> 72.5</u>

72.5 +72.5 + x = 180

72.5 +72.5

x + 145 = 180

x =  35.

Hope This Helps!

The bench costs $450.
You first need to subtract the difference between the garden table and the bench from the total so they are equivalent, and then divide by two to find what the bench is on its own.
(The garden table costs $536, by the way. To find that, you just need to add its half of 900, 450, to the 86 you subtracted initially.)
Tell me if this doesn’t make sense, it’s sort of hard to explain!

Find the missing angle measures in the triangles
Svetllana [295]

For the first triangle, I believe the given angles are 85 and 53. If I am incorrect, please let me know and I'll resolve it.

The answer for 1 would be 42.

2nd triangle- 69 is the missing angle measurement.

3rd- 64 degrees.

4th- 53

The reasoning behind all of these: The total of all three interior angles should be 180 degrees. So when you add the two GIVEN angles, and subtract that from 180, this answer is your missing angle.

(Also, for any other site or anything, it might be best to block out your name)
